At the boys's changing area in the Prison Block, the boys finish bathing with Shingo not present. Kiyoshi tells Gakuto that he is able to endure their social exclusion of him without his help as acting otherwise would be to Gakuto's detriment. However, when Shingo returns, an ashamed Gakuto leaves the shower upset at his lack of bravery. Kiyoshi notices food on Shingo's cheek which he removes. A few days later, the boys are heavily beaten for looking at schoolgirls upskirt, with the exception of Shingo and Andre. In the mess hall of the Prison Block, Jo nearly beats up Andre after he involuntarily pushes his ant farm over and has to be restrained by Kiyoshi and Gakuto. At the guard office that day, Shingo meets the Vice-President who coerces him into telling her of Jo and Andre's confrontation and the rising tension between the boys. However, Meiko blackmails him with the boys learning of his treachery to become her informant in return for good food before allowing him to leave. Afterwards at the USC's office, Meiko reports Joe's protective attitude toward his ants to Mari, who decides to include Jo's ants to their plan and intensify their pressure on the boys to increase their stress.
